+# The `su` command
+
+In linux, `su` allows you to run commands with a substitute user and group ID.
+
+When called without arguments, `su` defaults to running an interactive shell as root. 
+
+## Example :
+
+```bash
+$ su
+```
+
+In case that you wanted to switch to a user called `devdojo`, you could do that by running the following command:
+
+```
+$ su devdojo
+```
+
+## The syntax of the `su` command is :
+
+```bash
+$ su [options] [-] [<user>[<argument>...]]
+
+```
+
+## Options :
+
+```bash
+-m, -p         --> do not reset environment variables
+-w             --> do not reset specified variables
+-g             --> specify the primary group
+-G             --> specify a supplemental group
+-l             --> make the shell a login shell
+-f             --> pass -f to the shell (for csh or tcsh)
+-s             --> run <shell> if /etc/shell allows it 
+-p             --> create a new pseudo terminal
+-h             --> display this help
+-v             --> display version
+```
